Mathematics

Answer:

4 7/8

Step-by-step explanation:

3 1/4 / 2/3

convert mixed numbers to improper fractions: 3 1/4 / 2/3

13/4 / 2/3

apply the fraction rule: a/b / c/d = a/b * d/c

= 13/4 * 3/2

multiply fractions: a/b * c/d = (a * c)/(b * d)

= (13 * 3)/(4 * 2)

multiply the numbers: 13 * 3 = 39

= 39/(4 * 2)

multiply the numbers: 4 * 2 = 8

= 39/8

convert improper fractions to mixed numbers: 39/8 = 4 7/8

= 4 7/8

Answer:

Step-by-step explanation:                    

4x -39 > -43                                            8x + 31 < 23

Add 39 to both sides                              Subtract 31 from both sides

4x -39 + 39 > -43 + 39                           8x + 31 - 31 < 23 - 31

Simplify                                                   Simplify

4x > -4                                                     8x < -8

Divide both sides by 4                             Divide both sides by 8

4x / 4  > -4 / 4                                          8x / 8  <  -8 / 8

Simplify                                                    Simplify

x > -1                                                         x < -1

the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?
FinnZ [79.3K]
ANSWER

The other zero is

x =  - 10

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.


We were given that the axis of symmetry of the quadratic equation is
x =  - 3


We were also given that, one of the zeroes of the quadratic equation is
x = 4


Let the other zero of the quadratic equation be
x = p

,then, we apply the midpoint formula to find the value of
p

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,




\frac{x_1 + x_2}{2}  = axis \: of \: symmetry

We substitute to obtain,

\frac{p + 4}{2}  =  - 3



We multiply through by 2 to get,

p + 4 =  - 6



This implies that,

p =  - 6 - 4

p =  - 10

Write the result of (4+9i)(7-4i) in a+bi form​
Serhud [2]

ANSWER

(4 + 9i)(7 - 4i) = 64 + 47i

EXPLANATION

The given complex number expression is:

(4 + 9i)(7 - 4i)

We expand using the distributive property to get;

(4 + 9i)(7 - 4i) = 4(7 - 4i) +  9i(7 - 4i)

(4 + 9i)(7 - 4i) = 28- 16i +  63i - 36 {i}^{2}

Recall that,

{i}^{2}  =  - 1

Our expression now simplifies to:

(4 + 9i)(7 - 4i) = 28 + 47i  + 36

(4 + 9i)(7 - 4i) = 64 + 47i
